Abstract
The utility model provides a square lithium battery shell, belonging to the technical field of lithium batteries and solving the problem that the conventional lithium battery is poor in a shake-proof effect. The square lithium battery shell comprises a square shell body and covering plates, wherein the covering plates are respectively arranged at two end parts of the shell body and are used for sealing the shell body; the covering plates are provided with liquid filling holes communicated with the interior of the shell body; and moreover the covering plates are provided with through holes through which the lithium battery can penetrate out; support pieces with which the electrodes of the lithium battery can be supported are arranged inside the shell body; and the end parts of the support pieces are fixed on the inner wall of the shell body. The square lithium battery shell has the advantages of simple structure, reasonable design, good shake-proof effect and the like.
Description
Technical field
The utility model belongs to technical field of lithium batteries, relates to a kind of quadrate lithium battery shell.
Background technology
Lithium battery is owing to have advantages such as in light weight, that volume is little, capacitance is big, charging rate is very fast, is widely used on all kinds of numbers, the communication product such as notebook computer.Yet, lithium battery is used for moving occasion or the more violent occasion of vibration, when for example being used for motor vehicle, military use etc., the wild effect of battery quality has but taken place.Through long-term use, the wild effect of lithium battery quality when finding in this type occasion, to use, quality Control during Production problem no thanks to, and relevant with the structure of lithium battery.
The lithium battery of this type occasion use at present is generally quadrate lithium battery, comprises housing and the both positive and negative polarity pole piece, barrier film and the electrolyte that are contained in the housing; Pole piece is provided with lug, housing one end opening, and cover opening by cap; Cap and housing ask through welding and form hermetically-sealed construction that said cap is provided with two electrode fairleads, is connected with anode electrode deriving structure and negative electrode deriving structure respectively; Wherein, described electrode deriving structure is that electrode lug, sealing ring, electrode punching are fastened on the cap with screw; Perhaps, the electrode lug is screwed on the metal electric pole, and electrode column is screwed on cap and draws.This structure is in the process of vibration, and the position changes between electrode slice and the housing, causes battery to damage, and useful life is low.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of well-set quadrate lithium battery shell.
The purpose of the utility model can realize through following technical proposal:
A kind of quadrate lithium battery shell; Comprise the housing that is square and be located at the cover plate that place, housing both ends seals this housing respectively; Have the liquid injection hole that is communicated with enclosure interior on the described cover plate, and on described cover plate, have the through hole that supplies electrode of lithium cell to pass, it is characterized in that; Have in the described housing the passive strutting piece of electrode of lithium cell, the end of said strutting piece is fixed on the inwall of housing.
Effectively electrode of lithium cell is supported through strutting piece is set, in violent vibrations process, prevent the relative change of electrode of lithium cell and cover plate position, prolonged the useful life of lithium battery.
In above-mentioned quadrate lithium battery shell, described strutting piece is strip and on this strutting piece, has the fixing hole that is complementary with electrode of lithium cell, and described electrode of lithium cell is located in this fixing hole.
Strutting piece simple in structure just is fastened in the housing, when cover plate is fixing with electrode of lithium cell, increases strutting piece fixing to the electrode of lithium cell other end, and shockproof effect is better.
In above-mentioned quadrate lithium battery shell, described strutting piece is fixed on the inwall of housing under the effect of self elastic force.
In above-mentioned quadrate lithium battery shell, described strutting piece is processed by plastic material.
In above-mentioned quadrate lithium battery shell, described housing and cover plate are processed by stainless steel material, and described cover plate is through the end place of laser welding at above-mentioned housing.
Compared with prior art, this square li battery shell has the following advantages:
1, simple in structure, reasonable in design, better through increasing the shockproof effect that strutting piece obtains, it is longer to use the lithium battery of this quadrate lithium battery shell to benefit from the life-span.
2, cover plate and housing are fixed together through the laser welding mode, and connected mode is simple, effectively electric core are hedged off from the outer world, and prevent the leakage of electrolyte.
Description of drawings
Fig. 1 is the structural representation of this square li battery shell.
Among the figure, 1, housing; 2, cover plate; 21, liquid injection hole; 22, through hole; 3, strutting piece; 31, fixing hole.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1; The shell of this quadrate lithium battery, it comprises the housing 1 that is square and is located at place, housing 1 both ends respectively to the cover plate 2 that this housing 1 seals, on cover plate 2, has the liquid injection hole 21 with housing 1 internal communication; And on cover plate 2, has the through hole 22 that supplies electrode of lithium cell to pass; In order to strengthen the shockproof effect of lithium battery, in housing 1, be provided with the passive strutting piece 3 of electrode of lithium cell, the end of this strutting piece 3 is fixed on the inwall of housing 1.
In the present embodiment, effectively electrode of lithium cell is supported, in violent vibrations process, prevent the relative change of electrode of lithium cell and cover plate 2 positions, prolonged the useful life of lithium battery through strutting piece 3 is set.
Concrete structure is as shown in Figure 1, and this strutting piece 3 is strip and on this strutting piece 3, has the fixing hole 31 that is complementary with electrode of lithium cell, and electrode of lithium cell is located in this fixing hole 31.The strutting piece 3 that this place is provided with simple in structure just is fastened in the housing 1, when cover plate 2 is fixing with electrode of lithium cell, increases the fixing of 3 pairs of electrode of lithium cell other ends of strutting piece, and shockproof effect is better.
